Title: System for constituting radio equipment
Inventor: SATOU MASAHIRO
IPC: H04B1/40
Filed: 1982-05-22
Abstract: PURPOSE:To obtain a local oscillating signal and a transmitting signal of a receiver having high frequency stability, by controlling two PLL circuits by an output of one reference oscillator. CONSTITUTION:A reference signal fREF1 from a frequency divider 12 is applied to one input of a phase comparator 14 constituting the PLL circuit and an output frequency-dividing an output from a voltage controlled oscillator 16 by a variable frequency divider 17 is applied to the other input. Thus, an output having a frequency of NfREF1 is obtained from the oscillator 16, where the frequency dividing ratio of a frequency divider 17 is denoted by 1/N. An output of the circuit 13 is transmitted to a receiver as a local oscillating signal and applied to a mixer 23 forming the PLL circuit 19. A reference signal fREP2 from a frequency divider 18 is applied to one input of a phase comparator 20 forming this circuit 19, and an output obtained by mixing 23 an output signal from a voltage controlled oscillator 22 and an output from the circuit 13 and frequency- dividing the output of the mixing at a frequency divider 24 (frequency dividing ratio 1/P), is applied to the other input. The output of the oscillator 22 is given to a transmitter.

Title: Rice cooker
Inventor: MIYAKE KAZUYA
IPC: A47J27/00
Filed: 1994-04-25
Abstract: PURPOSE:To prevent the overheating of rice while preventing condensation on a lid body, even when a shell heater and a lid heater are controlled in the same sequence. CONSTITUTION:The side of a pot is heated with a shell heater 7. A lower lid surface plate is heated with a lid heater 29. After letting the rice steam following finish boiling, to prevent condensation, the shell heater 7 and the lid heater 29 are controlled to energize or deenergize. The energization rate at this moment is set at a heating value lower than a necessary heating amount for keeping the rice of half amount of the minimum cooking-possible quantity at a heat reserving temperature. Thus, a heat reserving heating control means 61 controls the shell heater 7 and the lid heater 29 to a heating value lower than a necessary heating amount for keeping the rice of half amount of the minimum cooking-possible quantity, thereby requiring no remarkably long time for lowering the temperature of the rice.

IPC: H01S5/125
Filed: 1980-06-26
Abstract: PURPOSE:To contrive to make a single mode by having buried structure of the active layer and to reduce the oscillation threshold value for the subject semiconductor laser by a method wherein the Fresnel reflection of the end section on the active  layer is removed and a single axis mode laser, which can be oscillated by Bragg reflection by grating alone, is obtained. CONSTITUTION:An N type InP layer 13 is laminated by performing an epitaxial growth along the convex section 12 on the substrate 11 having a narrow-stripped convex section 12 and on the layer 13, an active layer 14 of N type InGaAsP, a P type layer 15 and a waveguide passage layer 16 of P type InGaAsP, having grating sections 17 and 17', are epitaxially grown.

Title: Rotary coating apparatus
Inventor: EMA HIDEAKI
IPC: H01L21/027
Filed: 1989-04-06
Abstract: PURPOSE:To prevent the release of the solid substance bonded to a bottom or side surface and to stably obtain a uniform film by providing the bottom and side surfaces in a rotatable manner centering around a rotary table 2 and providing a liquid supply means for supplying a liquid wetting the rotating bottom or side surface. CONSTITUTION:A bottom surface 3 and a side surface 4 are rotated along with the rotation of a rotary table 2 and the coating solution supplied to the object to be coated placed on the rotary table 2 is shaken off by centrifugal force to be adhered to both of the side surface 4 and the bottom surface 3. Since the side surface 4 and the bottom surface 3 are wetted with the liquid supplied from a liquid supply means 6, the coating solution adhered to the side and bottom surfaces 4, 3 is not dried and solidified to become a single layer film or a structure wherein fine solid particles generated from the coating solution are strongly bonded to each other and prevented from release. By this method, the solid substance adhered to the bottom and side surfaces is prevented from release and a uniform film can be obtained stably.

Title: Ceramic board and its manufacture
Inventor: INAGAKI KIYOSHI
IPC: H05K3/46
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To sufficiently secure junction reliability of a flip chip, even if the surface of a via conductor exposed to the surface of a board is used as a pad as is. SOLUTION: Via conductors 14a and 14b on the uppermost layer, which are exposed to the surface of a ceramic board, are formed in two layers through hole burying printing conducted two times. The part 14b, except for the surface part 14a in the via conductors on the uppermost layer, is formed similarly by conductive paste to the via conductor of the other layer. The via conductor surface part 14a is formed by conductive paste, whose solder wetting property if higher than that of the other via conductor 14b. In a conductive paste used for the via conductor surface part 14a, the mixing quantity of sintering control additive is less than the conductive paste used for the other via conductor 14b used, and therefore the solder wettability of the via conductor surface part 14a is improved.  Then, the surface of the via conductor surface part 14a is polished, flattened and is used as a pad for flip chip.

Title: Photo-electric type smoke sensor
Inventor: TOKI AKIRA
IPC: G08B17/107
Filed: 1988-04-08
Abstract: PURPOSE:To improve the detecting sensitivity of smoke by preventing a light from being incoming to a photo detecting element when the smoke does not exist in a darkroom and decreasing a background noise. CONSTITUTION:For the light projected from a light emitting element 21 to a darkroom 13a, an irradiation angle is limited by a shading piece 34e and concerning a photo detecting element 22, a photodetection angle is limited by shading walls 35d. Then, overlapping between an irradiating range by the light emitting element 21 on the inner peripheral surface of the darkroom 13a and a photo-detecting range by the photodetector 22 can be avoided. When the smoke does not exist in the darkroom 13a, the light is prevented from being incoming to the photodetector 22 and the background noise is decreased. Thus, the difference of photo-detecting light quantity of the photo-detecting element 22 can be obtained for a case that the smoke exists in the darkroom 13a and a case that the smoke does not exist. Thus, the detecting sensitivity can be improved to the smoke.

Title: Branch and relay method
Inventor: ARINO YOSHIKAZU
IPC: H04J3/08
Filed: 1985-04-24
Abstract: PURPOSE:To prevent a fault at the input side from being effected on the output side by sending a multiplex signal having an independent frame phase to a multiplex transmission line at the output side even when a multiplex transmission line at the input side causes a fault. CONSTITUTION:Since the branch and insertion of the branch insertion circuit 13 and the read from a storage circuit 11 are operated by a unique frame phase pulse generated from the frame phase generating circuit 12, even when a fault takes place in a multiplex transmission section at the input side and the 1st frame phase generating circuit 10 causes out of synchronism, the unique frame synchronizing signal is sent to the multiplex transmission line at the output side. That is, this system has an advantage that a fault at the input side is not affected onto the multiplex transmission section at the output side. When the fault is restored and the 1st frame phase generating circuit 10 uses a reception signal to establish the synchronization, the channel causing the fault is recovered by writing each channel signal sequentially from an address zero of the storage circuit 11.
